If f(x) = -4x + 3 and g(x) = 3x^2 + 2x - 4 find (f+g) (x)
Answer:
3x^2-2x-1
Step-by-step explanation:
Here, we want to find (f + g)(x)
Mathematically, that will be f(x) + g(x)
= -4x + 3 + 3x^2 + 2x -4
= -2x-1 + 3x^2
= 3x^2-2x-1

A car is traveling at a speed of 72 kilometers per hour. What is the car's speed in kilometers per minute? How many kilometers will the car travel in 2 minutes?
Do not round your answers.
72/60 to get the speed per minute which is 1.2 miles per minute. From there you can just multiply by 2 to get how far the car will travel in two minutes which is 2.4 kilometers. Not rounded btw.

Question 3: Jason
receives $40 from
selling 5 adult tickets
and 8 students tickets.
.write an equation to
represent the situation.
Answer:
$40 = 5a + 8s
Step-by-step explanation:
For this question all we need to know is that $40 is equal to 5 prices of the adult tickets plus the 8 prices of the student tickets. From here we can just give a variable to each price and make an equation, like so
Let "a" be the price of the adult ticket and
Let "s" be the price of the adult ticket, then....
$40 = 5a + 8s
(Just to make sure you understand I will repeat. 5 comes from he fact hat there were 5 adult tickets sold which means that there is 5 adult ticket prices in the $40, and exactly the same reasoning goes for the student tickets, 8 students tickets were sold which means the is 8 prices of the student ticket inside the $40.)

John is buying food for his cat, Fluffy. Fluffy LOVES a fancy wet food which costs $1.50 per day. Fluffy will also tolerate dry food which is $0.75 per day. John wants to spend at most $9.00 on cat food each week
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.
Hence:
x + y = 7 (1)
Also, John wants to spend at most $9.00 on cat food each week. Hence:
1.5x + 0.75y ≤ 9 (2)

The figures are similar, and the ratio of the perimeters is 2 : 5. Find x.
Answer:
x=3.2
Step-by-step explanation:
8*0.4=3.2
We have that for the Question "The figures are similar, and the ratio of the perimeters is 2 : 5. Find x." it can be said that the perimeters of x is
x=3.2
From the question we are told
The figures are similar, and the ratio of the perimeters is 2 : 5. Find x.
Generally the equation for the the ratio is mathematically given as
2=x
and
5=8
Therefore
[tex]x=\frac{2*8}{5}[/tex]
x=3.2
Therefore
the perimeters of x is
x=3.2

work out 1/2 x 7 giving your answer as a mixed number
Answer:
[tex]4\frac{1}{2}[/tex]
Step-by-step explanation:
This question is basically saying: what is half of 7, or what is 7 divided by 2?
Based on this, it can be written both of the ways as:
»» [tex]\frac{1}{2}[/tex] of 7 OR 7 ÷ 2
So, just solve using either one and you’ll get 4.5 or [tex]4\frac{1}{2}[/tex]. But since the question wants the answer to be a mixed number, then choose [tex]4\frac{1}{2}[/tex].
Hope this helps! :)
